Gladio's ears perk right up at the laugh and he leaps back, play bowing at the laugh. Yes! Come play with him! When he gets older, a lot of this fun-play attitude will be gone in the wolf but right now he's still young enough to have it and definitely excited to have a playmate.

Human Gladio might very well be embarrassed about this, though. He tries so hard to seem adult as he needs to be.

There's a huff of sound, not quite a bark, but he isn't a dog. The werewolf is quieter, even if massively large. Noctis might never have seen Clarus when he shifts, or how big the man is on two legs instead of four, but it's clear Gladio will be almost unreal in size someday.
